What role does moral reasoning play in moral judgment? More specifically, what causal role does moral reasoning have in the production of moral judgments? Recently, many philosophers and psychologists have attempted to answer this question by drawing on empirical data. However, these attempts fall short because there has been no sustained attention to the question of what moral reasoning is. This paper addresses this problem, by providing a general account of moral reasoning in terms of a capacity, and suggests how this account of moral reasoning can provide a way forward in current debates.
